This research study is a Phase I clinical trial. Phase I clinical trials test the safety of an investigational drug, combination of drugs, or combination of drugs with radiation. Phase I studies also try to define the appropriate dose of the investigational drug to use for further studies. "Investigational" means that the combination of drugs and radiation is still being studied and that research doctors are trying to find out more about it. It also means that the FDA has not approved bevacizumab with doxorubicin and radiation for your type of cancer.
